(01.51-4379 This invention relates to .a .sspinning :irame :of the ring .type whichia Jowof acoonerating rings and spindles .is .provided .at each side of ithe frame and .in which -.a relative vertical movement takes place between the rows of .rinss and :the rows of spindles iniefiecting thepperationpf the machine.

The .object ,of the .invention .is to provide :for accurate .relati-ve ,vertical .movement of .the mings and spindles, to do this with means which will allow .free access :beneath Jihe machine so as not to interfere .with .cleaning .and to enable the maximum :ttaverse or uiclatite vertical movement .to the .seeured with any igwen .height of frame.

The ,nature .obiects -of :the {invention will appear .more aully ,trom r-the 'aocommnying description and -.drawinas :and .will .be particularly pointed out in the claims.

Since .the invention rel-ates ale-buttons "feature or rthe spinning irame, it .is ionly .neeessary a0 illustrate .and describe swthmontions :o'f ea .spin ning .frame .with which the linventioniis ipanticu larlyconcerned. The-intention is conveniently illustratedinconnection .vtitheistandard .typeof spinning frame such, vfor example, as .shown .in thepatent tomwen No hiifl fifia granted January 26, 1932. In such la .irame .the spinning rings are mounted .onrailseetions Eat each side .of :the frame-imiixed .vertical position while ithespindles are mounted 4m rail :sections at .eaehfside .of lthe frame connected by transverse iarches .given .a vertical. movement tocause the spindles toicoqpcrate with the rings in the spinning reparation. But in ithe'broader'acope of the invention it is immaterial whether the ring rail sections are fixed and the spindle mil .mntimis vertically movable, or vice versa.

The drawings also, for 'thepurpose of clearly illustrating the details of a preferred construction of thefinven'tion,sshowsomecofithe elements out of their proper proportion with respect to other elements, but since the general construetion and operation of "these sp'inn'ing "frames is well known to those skilled in the art, the proper proportions will readily be determined.

In the drawings,

Ateachsideiof the spinning frame this?intcrmediatessection'presents a wentical lframe member :the :one at :the side shown in Fig. ".1 being illustrated with :the iconnection 5 extending therefrom :back to the other side. At the bottom uthese iintermediate sections are :iaupporzted :directiy am fiche floor usually :by bsishaped Soot pieces LB bolted thereto.

Each one of these vertical frame members :4, in this imvention, mas :secured thereto an upper bracket 21 and allowerkbnacket B. 'illheserbrachets are :sconveniently ssecured Lin eplace by ?being clamped and zbolted zto xusual flanges of -,the vertical :frame imemhers :4. :In the :consitruction illustrated where :the-aring :rails are :fixed and the spindle rails movable, the "ring rail :sections 9 are itigidly :supported (on dihe upper brackets 1 and =ext'end ilong'rtudinally :at each side of the spinning iframe. :jillustrated in fiig. 3 search ring rail section 2-9 is :seated -;up on :iupper face of the brackets .1 andzheldlin :place by v:bolts t0.

'HEhes'e rail sections are of the-zusual gconstruction, provided with {the usual spinning rings mounted in the :iusual manner concentric with apertures -"spaced ilongitudinally of .the :xail Ysec- Mons as mequired :by :the urumber of spinning elements.

spindle-m'ail sections in this ftypemfs-spinriing name, and iillustrated in "the aforesaid patent to Ewen, are given their werticalimomement by a plurality 50f vertically zmoved rtransversearch'esextendingzacross the :frame and1sup porting at :each {end :the spindle sections. One end ll of one of these transverse arches is as shown in detail in Fig. 2. The number of these transverse arches depends in general upon the length of the spinning frame, one or more being placed between each end frame and the next intermediate frame section, and. one or more between each pair of intermediate frame sections. These transverse arches are given the required vertical movement by any suitable means such as the flexible connectors l2 extending therefrom over the pulleys l3, operated by the usual mech- 3 anism in one direction and by the counterbalances L4 in the other.

Each spindle rail section l5 has mounted thereon the usual spindles carrying bobbins l6, driven by the usual means and cooperating with the spinning rings in the spinning rail sections, the construction being the same at each side of the spinning frame.

The connection between a spinnin rail section I5 and the end [1 of one of the transverse arches l I shown in Fig. 4, provides a simple means for a relative adjustment between the rail section and the end of the transverse arch. As illustrated a bolt l8 clamps the rail section l5 to the end I! of the transverse arch with this bolt passing through an enlarged aperture 170 in the end I]. Thus the relative position of the rail section with respect to the end of the transverse arch may be adjusted and then the bolt clamped up by the nut 19 to hold the parts firmly in adjusted position.

The vertical movement of the spindle rail sections is accurately guided by means of vertical guide rods positioned at each side of the spinning frame with these guide rods alined respectively with the vertical frame members and extending between the lower and upper brackets secured thereon. One of these guide rods 20 is illustrated in Fig. 2 thus alined with and supported from one of the vertical frame members 4. At its upper end the guide rod 20 is provided with a reduced end 2| seated in a bore in the upper bracket 1. At its lower end it is clamped by a set screw 22 in a foot piece 23 seated on the upper face of the bracket 8. This foot piece is clamped to the bracket 8 by one or more bolts 24 passing through enlarged apertures in the bracket 8 so that the foot'piece may be shifted in any radial direction to bring the guide rod into exact vertical position.

Each guide rod 20, as shown more in detail in Fig. 3, passes through a bushing 25 secured in the spindle rail section l5. This bushing has a sliding fit on the guide rod and passes through a slightly enlarged aperture in the rail section so as again to enable accurate adjustment to be made between the rail section and the guide rod. The bushing 25 is conveniently shown as having an upper flange seated on top of the rail section and a screw threaded lower end carrying a nut 26 enabling the bushing to be clamped firmly to the rail section in adjusted position.

It will thus be seen that these spindle rail sections at each side of the spinning frame are accurately guided in their vertical movement by the guide rods and that, since the bushings which slide on the guide rods are located entirely in the rail sections, they are of short length and cannot tip and bind on the guide rods during the vertical movement. Moreover, the guide rods and their supports, being positioned in alinement with the vertical frame members 4, do not obstruct the spaces between the end frames and the intermediate frame section and between the intermediate frame sections so that ready access may be had for cleaning beneath the spinning frame. Furthermore, it will be seen that the downward traverse of the spindle rail sections is limited only by the engagement of the bottom of the spinning rail with the foot pieces 23 on the lower brackets 8 which are positioned close to the floor. Thus the maximum traverse may be secured.

Having thus described the invention, What is claimed as new, and desired to be secured by Letters Patent, is:

1. In a spinning frame having a plurality of vertical frame members at each side, a plurality of vertically movable transverse arches extending between pairs of the vertical frame members at each side, a pair of ring rail sections one at each side of the frame, and a pair of spindle rail sections one at each side of the frame, the combination of upper and lower brackets on the said vertical frame members, a plurality of said vertical guide rods-each alined with one of the vertical frame members and extending between the lower and upper brackets thereon, one pair of said rail sections being rigidly supported on the upper brackets, the other pair being supported on the ends of the transverse arches, and bushings mounted in the latter pair of said rail sections one on each guide rod and having a slid ing fit thereon.

2. In a spinning frame having the construction and combination of elements defined'in claim 1, the combination therewith of means for adjusting the lower end of each guide rod radially in its lower bracket and means for relatively adjusting each end of the transverse arches with respect to the rail sections supported thereby to insure accurate vertical movement of the rail sections. V

3. In a spinning frame having a plurality of vertical frame members at each side, a plurality of vertically movable transverse arches extending between pair of the vertical frame members at each side, a pair of ring rail sections one at each side of the frame, and a pair of spindle rail sections one at each side of the frame, the combination of a plurality of said vertical guide rods each alined with one of the vertical frame members and supported therefrom, one pair of said rail sections being rigidly supported from said vertical frame members, and the other pair being supported on the ends of the transverse arches and guided in their vertical movement by said guide rods.
